PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 394,451, dated December 11, 1888.

Application filed April l1, 1888.

To all wtont it may concern:

Be it known that we, EMMoNs R. BOOTH, of Kirkwood, in the county of St. Louis and State of Missouri, and JOHN R. XVILLIAMS, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Paper-Cutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a front elevation of the machine with sectional rolls, with part broken away to show the thumb or finger gate in the tensionplates that provides a convenient catch-hold of the paper for a redraw and cut, and the coadjutory strap and spiral and tension springs. It also shows a detail of the upper paper roll, whose shaft may have its bearings in avertical extension of the basement-frame, as in the Patent No. 379,444, issued to us March 13, 1888, or in any other suitable supporting-frame. Fig. II is an end elevation of the machine, and shows the relative course of the paper from two rolls through the second tension-boxing and the rigidly-secured knife that surmounts said boxing. Fig. III is a detail section of a modification, and shows the second tension -boxing, the tension plates with their individual springs, and beaded heads. It also shows the relative course of the paper from separate rolls and the corrugated knife that surmounts the tensionboxing and severs the paper. Fig. IV is a detail elevation of a modification, showing a detached pedestal that supports the second tension-boxing, the tension-plate, the roller that carries the paper, and the rigidly-secured surmounting knife that severs said paper. Fig. V is an enlarged detail of one of the tension-plates, and shows its pressure-spring and thumb or linger gate that provides a facile catch-hold for the draw end of the paper. Fig. VI is a detail modification of the second tension-springs, in which one spring at each end commands the tension-plates; and Fig. VII is a side elevation of a modifi` cation of the machine, in which the vertical pedestal that carries the knife, &c., is cast integral with that which carries the paper roll. It also shows an angular terminal to the shaft Serial No. 270,304. (No model.)

on which the roll rotates, which is seated Within a forked tight bearing that projects from the main pedestal and holds said shaft from rotary movement in its seat.

This invention relates to devices for holding paper rolls and the manipulation of the paper in the process of cutting; and the invention consists in features of novelty hereinafter fully described, and pointed out in the 6o claims.

Referring to the drawings, in which similar figures of reference indicate like parts in all the views, l l represent the lower sectional rolls, and 2 a portion of the upper pa- 65 per roll. The rolls are wound around or inclose sleeve bobbins or spools 3, which may either be of length to correspond with that of the roll or maybe sectional, being then seated to the required length at each end of the cy-l 7o lindrical aperture within the roll. The paper rolls may be either wound on said spools at the mills, or, especially when sectional spools are used, the rolls may be furnished with open cores and the sectional spools driven in from each end. The spools and rolls are carried on the axle 4, which may either have tight bearings within thc spools and run in loose bearings within the forks 5 and the main standards (i of the frame, from 8o which said forks project, as shown in Figs. I and Il, or the axles may have angular terminals 7 to provide a tight bearing within said forked boxing, and then the spool, with the roll it carries, works with a loose bearing around the stationary shaft, as shown in the modification in Fig. VII.

8 represents the platform or base-plate, of either wood or metal, to which the flanged feet J of the standard (which is preferably of 9o bracket-bearings, as also shown and described 1 oo in said patent, or by any other suitable means, as no novelty is claimed for the means of sup- The upper roll,

porting said upper roll other than that by which the lower roll is supported. Y v

l2 represents the flanged heads of the main standards 6, to which the top or cap plate is secured, as stated, by any suitable means. The front portions of said heads have enlarged projections that are surmounted by inclined edges 13, to which are secured the knives 14, which are fastened to said inclines by screws 15, or by any other suitable means, and together form a box bearing-chamber, 16, in which'is carried the shaft 17, that has its bearings (either loose or tight) in the corresponding projecting flanges that constitute the side walls of the boxing, and the said shaft carries a loose rot-ary sleeve, 18, that forms a combined guide and anti-friction roller. Within said boxing also work the second tensionplates, 1 9, whose number-one, two, or more-corresponds with that of the paper-rolls. The said tension-plates bead around and have tight bearings on the rods 20, that have loose bearings in the projecting flanges that form the side walls of said box bearingchamber.

The tension-plates are preferably looped around to form beads 21 at their free ends, and the lower one, and, when required, the upper also, is provided with a spring, 22, at each end, whose fast end is rigidly attached to the tension plate, and it winds spirally around the shaft that carries said tensionplate and is held to its spring action by the staypin 23. The upper tension-plate, and

Athe lower one also, when preferred, is provided with a thumb or finger gate, 24, to fa cilitate the grasping of the ends 25 of the paper to draw it out ready for cutting.

26 represents washers that are mounted on the shaft or shafts that carry the rolls and press against the ends of said rolls under the impingement of the spiral springs 27, that are also mounted on said shafts and are backed up by the main standards of the frame and the forks 5, that project therefrom to exert an end tension on saidwashers 26, and by their means on the rolls.

28 represents strap-springs that are secured to the inside of the flanged heads of the main standards by rivets or screws 29 and press against the aforesaid washers 26 beyond the action of the spiral springs, to re-enforce the tension of said spiral springs as coadjutants thereto.

It will be seen that as this system of double spring-tension is, unlike the peripheral tension in common use, exerted solely on the ends of the rolls, and that not far removed from their center, it follows that an even tension is always exerted on the rolls, and does not vary, as does the peripheral tension, when from the near exhaustion of the roll the pressure of the peripheral spring is also nearly or quite exhausted. 1

In Fig. III is shown a modification in which the box bearing-chamber wherein'the second tension-plates, &c., operate is detached from the roll-carrier frame and secured by screwbolts 30 to the counter or other convenient position handy to the clerk or operator that handles the paper. Sometimes there is not room for the rolls and their supporting-frame on the counter of busy retail establishments, in which case the fram e, with its rolls, can be located in any suitable position out of interference with the movements of the clerks, and either be elevated above the counter or placed down beneath it; or, as shown in said figure, by the direction from which the paper arrives, one roll may be located above the counter and the other be placed beneath it. In this modification we have also shown a modification of the knife, which is provided with a corrugation, 31, to stiffen the blade, which also carries a bead, 32, on its upper edge that has the double function of re-enforcing the attachment of the blade and guiding the ape proach of the paper from the upper roll.

It will be seen that in the modification in Fig. III, as also in those of Figs. IV and VII, the second tension-plates operate from beneath the paper against which they press; but we do not confine ourselves to that position, for, as shown in Figs. I and II, the lower tension-plate may be and is located above the paper, and in either case they eect the same pnrpose-viz., hold the paper that has just been withdrawn from the roll while it is being cut, and to hold the stub to 'present a convenient catch-hold for the next withdrawal.

In Fig. IV is shown another modilication, for use also in positions removed from the rolls, in which the aforesaid box bearing-chamber 16 surmounts an independent pedestal, 33, whose flanged foot may be secured to the counter or other suitable position by the screws 10. In this modification is also shown an anti-friction-roller guide, 34, whose pivotrod works in loose bearing in the sides of the boxing. The paper is shown in this gure in full line descending from an elevated roll and in dotted lines from a roll on the samelevel. In the figure showing this modification, as also in Fig. VII, single tension-plates only are shown; but we do not so coniine ourselves, for twin tension-plates that operate on paper delivered from two rolls may be used, as shown in Figs. I, II, III, and VI.

In Fig. VII is shown a somewhat similar modification to that described above in Fig. IV, in which the pedestal 33 is cast integral with the main standard that carries the roll or rolls. In this figure is also shown a modification of the second tension-spring, in which the stay ends 36 of the springs rest on ledges 37, that project inward from'the sides of the IOO IIO

boxing 16, and thus support the spring and the tension-springs, in which a single spring, 38, enforces the tension of both the upper and lower second tension-plates.

It will be seen that we show sectional rolls of the same width as the lower rolls and a single long roll above; but their relative positions may be reversed when preferred, and the sectional rolls may be of diverse widths.

le have shown two sectional rolls on one axle'and a single roll; but we do not confine ourselves to any definite number of rolls, for it is evident that the especial features of our invention can be applied to a larger or smaller number of rolls than those shown.

then there are sectional rolls on one shaft, an anti-contact washer, 38, is mounted on the shaft between said rolls.

lVe have shown and described coadjutant spiral and strap end-tension springs; but we may, especially with small rolls, use only the spi ral or the strap springs, as may be preferred, without the re-enforcement of the co-operative springs.

It will be seen that the beads 21 at the free ends of the second tension-plates, besides acting as anti-friction terminals to guide to a free passage of the paper on a draw, also direct the right presentation of the paper for a convenient catch-hold for a redraw.

XVe claim as our inventionl.
